REFRIGERATIHG APPARATUS.

Application filed November 6, 1924, 8er1a1 no. 748,2e8.- Renewed Fovember 27, 1926.

. The present invention relates to refrigeratin apparatus and particularly to mechanical re rigerating apparatus including an evaporator in which food and desserts are. con-= gealed or in which water is frozen.

@ne of the objects of the present invention is to freeze the water orcongeal the'food in a more eficient manner. This object is carried out by constructing the evaporator and no the container for said water or dessert in such a manner so that said container can be placed relatively close to the evaporator.

It is a further object of the present invention to provide for the ready removal of the container which is likely to be frozen upon its support.

Further objects and advantages of the resent invention will be apparent from the following description reference being had to the accompanying drawings, wherein a preferred form of the present invention is clearly shown. 7

Referring to the drawings, Fi 1 is a diagrammatic view of a mechanica refrigerating apparatus embodying the present invention. Fig. 2 is an enlarged fragmentary sectional view of the cooling unit showing a portion of the container, and Fig. 3 is a front elevation of the container showing same in the position in which it is placed for withdrawing same.

Referring to the drawings, a refrigerating apparatus is shown including a compressor 20 for expanding refrigerant contained within an evaporator 21 through the pipe 22 and for compressing the refrigerant and forcing same into a condenser 23, from where the condensed refrigerant is conducted by a pipe '24 to an expansion valve 25 which controls the flow of refrigerant to the evaporator 21.

The compressor 20 is driven by belt-and-pulley connections 26, 27 and 28, by a motor 30. The evaporator 21 comprises a series of coils 31. These coils form a support for a shelf 32 and are suitably connected with said shelf by soldering or brazing same as is shown at 33, in orderto provide for the ready conduction of heat from said shelf to the coils 31. Containers for water to be frozen or food to be congealed are slidably mounted 60 upon the shelf 32. The entire bottom wall 36 of the container 35 engages the top side of the shelf 32 and this relatively large contact in surface provides for the ready conduction of heat from the container 35 to the support 32. 3

Due to condensation, water is likely to freeze upon the shelf 32 and cause the-container*35 to be frozen tightly to the shelf. In order to'readily remove the container 35 from the shelf 32, it is necessary, first, to break the ice bond between said container and shelf. Therefore, the handle 37 for the container 35 is pivotally mounted at 38 u on extending pprtions 40 of the side walls 0 the container. .65

ownwardly extending arms 39 are formed integrally with the handle and are adapted to engage the shelf 32 when the handle 37 is moved to remove the container. This movement of the handle 37 will cause the container 35 to be lifted as shown in Fig. 3 and in the dotted-line position (Fig. 2), which will cause the ice' bond between the container 35 and the shelf 32 to be broken. The handle 37 and arms 39 form bell-crank leversand the construction and arrangement of said levers with respect to the shelf 32 is such, that by merely pulling the handle 37 h0rizon-..,v tally, for removing the container 35, a vertical movement will be imparted to the con.- 30 tainer for breaking the ice bond, whereby the container can be removed readily.

While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows:

1. A cooling device, comprising in combination, a plurality of cooling coils, a shelf supported by said coils, a slidable container supported by said shelf, and means pivoted to said container and having an arm' adapted to engage said shelf, for breaking an ice bond between the container and the shelf. 95

2. A cooling device comprising in combi-' nation, a plurality of ooolin coils, a shelf supported by said coils,a sli able container 3. A cooling device comprising in combi nation, a plurality of coolm coils, a shelf supported by said coils, a sli able container supported by said shelf, a handle pivoted to the container, and means associated with saidhandle and adapted to engage said shelf when said handle is rocked on its pivot, for breaking the ice bond between the container and the shelf.

4. .A cooling device, comprising in combination, a lurality of cooling coils, a shelf supported y said coils, a slidable container supported by said shelf, a movable handle pivoted to said container, and means carried by said handle and adapted to engage said shelf upon movement of the handle, for breaking an ice bond between the container and the shelf.

5.

6. Refrigerating apparatus comprising in combination,an ice-making container having a surface adapted to cooperate with a support, a handle movably secured to the con- -tainer, and means operated by movement of the handle with respect to the container adapted to separate the surface from such support when force is applied to the handle substantially parallel to the surface.

7. Refrigerating apparatus comprising in combination, an ice-making container having a surface adapted to cooperate with a support, a handle movably secured to the container, and means normally on one side of the plane of the surface operated by movement of the handle under the influence offorce substantially parallel to the surface to project on the other side of the plane of the surface.
